Do photos look worse on phones screen than on a computer?

http://forums.androidcentral.com – I went to buy an S4 having read about the vibrant and colorful Amoled screen. When I got to the shop I lined up an S4 side by side with an HTC One and compared images on the internet - mainly high quality landscape photos. I could not believe the difference. The HTC showed them up so much better. All images on the S4 were duller than the HTC. The consultant agreed with me but he described the S4 photos as just being more saturated and that the HTC screen is just brighter. He also said that the photos taken by the s4 would not look dull on another screen. I left confused and without a pho (HowTos)
